Where your data lives

What is stored

One record per reminder. Each holds the page address and title, the time you chose, and whatever else you set on it — a note, a tag, a folder, a repeat rule, a priority.

Two things are stored separately from the reminder itself, for different reasons:

• Page thumbnails, if you have them switched on. These are the largest thing Latr stores — roughly 12–40KB each — so they live under their own keys and are only loaded when the popup actually draws them.
• Your settings, including any sounds you have uploaded.

There is also a seven-day delivery log, so the popup can show you what fired recently even for a repeating reminder that has already rolled forward.

Where it physically is

In your browser's extension storage, on your machine's disk, inside your browser profile. Same place your bookmarks and history live. Nothing about it is unusual, and nothing about it involves us.

If you turn on sync, reminders also travel through your browser's own profile sync — Chrome's or Firefox's, the same mechanism that carries your bookmarks between your computers. That is still not a server of ours. Thumbnails never sync: a single one would exceed the per-item quota that mechanism allows.

The requests Latr makes

A free install makes none. That is meant literally rather than as a summary — there is no analytics beacon, no telemetry, no crash reporter, no font fetched from a CDN, no update ping of ours. The extension talks to your browser and to nothing else.

Two things can cause a request, and you cause both of them:

• Buying and activating Pro. Your licence key is sent to our one server route, which answers whether the key is real and ours. It is re-checked at most once a week. No reminder is ever attached to it — see activating your licence.
• Uninstalling. Your browser opens our uninstall page, because that is the only moment left to ask why. The address carries no query string at all: not your version, not your install age, not how many reminders you had. It is the same static page for everybody, and it learns only what you choose to type into it.

What Latr can read about your browsing

The title and address of one tab, at the single moment you save a reminder from it. Not before, not after, and never on a page you did not save.

That is a property of the permissions Latr asks for rather than a promise about behaviour — the install prompt asks for no access to your browsing history and no standing access to the sites you visit. Browser permissions explained goes through each one and what it is for.

Bookmark access is the one thing that would look alarming at install time, so it is not asked for at install time. It is optional, and it is requested by the import control in Settings at the moment you use it. If you never import bookmarks, Latr never has it.

Checking this yourself

Settings → About Latr has a privacy panel showing live figures rather than a policy: data sent, servers contacted, bytes stored on this device. On a free install the first two read zero.

If you would rather verify it than read it: open your browser's developer tools on the Network tab, then use Latr normally. Nothing of ours appears.

Taking it with you, or deleting it

• Backup and restore writes plain JSON you can read.
• CSV export opens in any spreadsheet.
• Settings → Your Data has a one-click clear-everything, and uninstalling the extension removes the storage with it.

There is nothing to close, no account to delete, and nobody to email. That is the point of building it this way.
